I just bought 20x PMC pm29F002T-12PC Flash ROMS, unfortunately they all have the boot sector locked which means it can't be re-flashed.
According to the datasheet there is a special code sequence that unlocks these - it says to call "the manufacturer". Unfortunately the manufacturer is no longer around. Does anyone know the unlock sequence - I've made my own programmer so can do any bit banging required.
While not really "vintage" I was hoping to use these parts with suitable pin swapping in a few of my vintage and homebrew machines.
Sorry if this is the wrong place to ask!
Cheers
